Joint Projective Invariants on First Jet Spaces of Point Configurations via Moving Frames
Leonid Bedratyuk
We consider the action of the projective group on the -fold first-order jet space of point configurations on the plane. Using the method of moving frames, we…

First order joint differential projective invariants
Leonid Bedratyuk
We present a complete algebraic description of the field of first-order joint projective invariants for configurations of \( n \) points in the plane, under the natural diagonal ac…
